Sounds like a Good Idea, but oh God.  It's daunting.  I have no idea
what Docker is, or how to use it ....

Did some web searching, and found *some* instructions.  Started off by
looking at the instructions for installing Docker on Ubuntu.  Did the
update step and the set-up-repository step.  That seemed to go OK.

Then I came to the "Add Docker’s official GPG key:" step.  Issued the
specified command

> curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg
> --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

And of course all hell broke loose.  Since curl is involved.  I got:

> curl: /usr/local/lib/libcurl.so.4: no version information available (required by curl)
> curl: symbol lookup error: curl: undefined symbol: curl_mime_free, version CURL_OPENSSL_4
> gpg: no valid OpenPGP data found.

So I'm back to the fact that my system is stuffed w.r.t. curl, but I
have no idea how to track down what's wrong. :-(
